A sump in a basement can be built in dry well form, allowing the sump pump to cycle less frequently (handling only occasional peak demand). A French drain can resemble a horizontal dry well that is not covered. A larger open pit or artificial swale that receives stormwater and dissipates it into the ground is called an infiltration basin or ...
In the UK, a cesspit is a closed tank for the reception and temporary storage of sewage; in North America, this is simply referred to as a "holding tank".Because it is sealed, the tank must be emptied frequently – on average every 6 weeks [2] – but frequency varies a great deal and can be as often as weekly or as rarely as quarterly.
A cistern (from Middle English cisterne; from Latin cisterna, from cista 'box'; from Ancient Greek κίστη (kístē) 'basket' [1]) is a waterproof receptacle for holding liquids, usually water. Cisterns are often built to catch and store rainwater. [2] To prevent leakage, the interior of the cistern is often lined with hydraulic plaster. [3]
Sump pumps are used where basement flooding may otherwise happen, and to solve dampness where the water table is near or above the foundation of a structure. Sump pumps send water away from a location to any place where it is no longer problematic, such as a municipal storm drain, a dry well, or simply an open-air site downhill from the building (sometimes called "pumping to daylight").
It discharges into a collection sump that might collect sewage from 2-6 houses and is located in a public area. Vacuum technology is based on differential air pressure. Rotary vane vacuum pumps generate an operation pressure of -0.4 to -0.6 bar at the vacuum station, which is also the only element of the vacuum sewerage system that must be ...
In mining the term sump is used to describe a hole made in the floor of a level in a working, in the direction of a lower level either for the purpose of testing the trend of an ore vein, or for the purpose of ventilation. The equivalent of a sump on a boat is the bilge. In the human eye, the vitreous humour has a minor role as a metabolic sump ...
Where the water supply system cannot reach the slums, people manage to use hand pumps, to reach the pit wells, rivers, canals, swamps and any other source of water. In most cases the water quality is unfit for human consumption. The principal cause of water scarcity is the growth in demand.
Pumping stations in sewage collection systems are normally designed to handle raw sewage that is fed from underground gravity pipelines (pipes that are sloped so that a liquid can flow in one direction under gravity). Sewage is fed into and stored in a pit, commonly known as a wet well. The well is equipped with electrical instrumentation to ...
